Title: Flowmeter with restricted orifice - is for particle suspension assessment using photocell sensor in orthogonal directions
IPC: G01N15/14
Filed: 1974-09-20
Abstract: The flowmeter (16) has the fluid suspension introduced into a cylindrical tube (26), which also contains a number of smaller tubes (32) to produce a substantially laminar flow regime. The suspension itself, typically containing flocullar matter (12), is introduced through a small tube (14) coaxial with the main tube. The flowmeter chamber is formed by four boundaries, two of which are flat and two of which are exponential curves (18) converging towards the centre orifice (20). The latter is optically examined by an apparatus including a light source (22), a focussing unit (33) and a photocell (24), which enables fractional light intensities to be measured in both (Y) and (Z) co-ordinate directions, these being orthogonal to the direction of fluid flow (X).

Title: Rotary dry shaver - has vanes extending sideways from driving dog bearing against slot walls in cutter member
IPC: B26B19/38
Filed: 1974-09-25
Abstract: The shaver has a detachable coupling between the cutter member and the driving motor, comprising a flat coupling dog engaging in a slot in the member.

Patent NL-8203619-A (NL)
IPC: G11B5/58
Filed: 1982-09-20
Abstract: For a controlled positioning of a read element relative to a track to be read during the read-out of such a record carrier, low-frequency tracking signals may be recorded in the tracks. Instead of adding separate tracking signals to the information signal, these tracking signals are represented by the d.c. content of the information signal. During conversion of the information words of the information signal into channel words steps are therefore taken to provide two channel words whose d.c. content is equal but opposite for each information word. The choice between these two channel words is made depending on a control signal which depends on the desired tracking signal.

Title: Process for the preparation of novel enzymes which catalyze the degradation and modification of lignin
Inventor: FARRELL ROBERTA
IPC: C12N9/08
Filed: 1986-07-14
Abstract: Novel lignin-degrading enzymes designated rLDM TM 1, rLDM TM 2, rLDM TM 3, rLDM TM 4, rLDM TM 5, and rLDM TM 6 are isolated and purified to the essentially pure form, wherein each rLDM TM  is substantially free of other rLDM TM  and native proteins, from the extracellular medium of a novel mutant microbe.

Patent PT-86658-A (PT)
IPC: E03F5/14
Filed: 1988-01-28
Abstract: A device for removing material screened or filtered out of a liquid flowing in a channel. It consists of an unpowered cylindrical grating that merges into a screw-type conveyor. The grating slants down, partly immersed in the liquid, to the bottom of the channel. The bars of the grating extend over its total length leaving longitudinal interstices between them. The upward-sloping conveyor comprises a housing, a shaft, and a worm and conveys the screened-out material to a depositing point. The worm picks up the screened-out material as it scrapes the bars of the grating and conveys the material upward, constantly keeping the grating clean. The grating bars (8) are more or less triangular or trapezoidal in cross-section, with rounded-off edges, and positioned in such a way that one side (25) of the triangular or trapezoidal cross-section is oriented tangential to the circumference of the conveyor worm (16). The longitudinal interstice (10) is narrowest at the least possible radius at that point, adjacent to which its open cross-section (28) expands over-proportionally in the direction (32) traveled by the liquid. The grating bars that demarcate the longitudinal interstices are connected by outside bracing bars (9).
